JOHN vAN, or CINCINNATI, OHIO.

IMPROVEMENT IN STOVE-DOORS.

Specification forming part of Letters Patent No. 116,646, dated July 4, 1871.

To all Iwhom it may concern:

Be it known that l, JOHN VAN, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Door for Stoves and Ranges, of which the following is a specification:

My invention consists in providing the re or oven-door of stoves and ranges with a shield or easing, which serves the several purposes of stiiiening the door, of coniining the heat within the stove or range, and as a guide or housing for the latch.

Figure l is a persl'iectivevi ew of a door embodying` my improvement, the door being shown open. Fig. 2 is a vertical transverse section through the closed door and adjacent portion ofthe frame or shell in the line of the bolt. Fig. 3 is a vertical transverse section in the plane of the rivets which fasten the guard-plate.

A represents a portion oi' the shell or body of the stove or ran ge. B is the main plate of a door, united by any customary hinges to said body. (l is a raised or chamber-ed plate, riveted on the front or outer side or face oi' the plate B, and having two notches, c c', in its upper and lower edges, respectively, for a vertical bolt, l), having shoulders d d that engage behind a catch, E, that project-s from the body7 and having a chainfered or beveled lower extremity, df', that rises over and engages within a sta-ple, F, when the door is closed. Projecting from the front of the latch is a knob or handle, Gr, whose shank plays in a slot, b, in the plate C, which slot limits the ascent and descent oi' the latch. The latch, as thus constructed, drops to its place by simple gravitation, but may be assisted thereto by a spring, it desired. The notches c c', being distant almost the entire length of the latch, the latter is held ilrmly, yet with great freedom of motion, and without liability to bind or stick in its bearings. The shield or guard-plate() serves to stili'en the door and to hold it to its proper shape, and also, by inclosin g a non-conducting air-space or jacket, connes the heat within the stove or range, so as to economize the same and render the room more agreeable to the operator.

l claim herein as new and oi' my invention- The arraiigement oi' the plates B, notched, raised, and slotted guard-plate C c c', vertical gravitating bolt D d 1I' d. G, and catches E F, substantially as and for the objects designated.

In testimony of which invention I hereunto set my hand.

JOHN VAN.
